NATIVE PLOW.

Application filed July 15-,

To all whom it may concern: I

Be. it known that I, MANUEL C. Anot'innnrs, a citizen of the Republic of Mexico, residing at Toluca, in the State of Mexico, Republic of Mexico, have invented certainnew and useful Improvements in Native Pl'ows, of which the following is a specification.

The present invention relates to improve ments in native plows and has. for its objects to reduce the resistance of the soil to the draft animals. in. using the plow, to reinforce the parts and to brace them, to provi-d'e easy means for the adjustable, attachment of accessory spreading and working blades, to provide suitable weed grubbers. or cutters, and to provide a construction facilitating the quick and simple attachment and replacement of the plow point, while automatically binding upon and preventing the accidental removal or displacement of the plow point.

In the accompanying drawings;

Figure 1 represents a perspective view of a native plow embodying-my invention, with. all of the blades, shares and point applied thereto;

Figure 2, a front elevation, broken away, thereof;

Figure 3, a detail perspective view of the large rear hinged binding collar;

Figure 4, a detail perspective View of the correspondingly shaped and constructed smaller front hinged binding collar;

Figures 5 and 6, detail perspective views of the supporting rods or brackets for the rear portions of the fixed shares 10;

Figure 7, an enlarged detail perspective view of the plow point and its shank;

Figure 8, a side elevation of the body of frame of a wooden native plow without the application of the metallic point, shares or blades thereto;

Figures 9 and 10, side views of the respec tive rigid shares 10;

Figures 11 and 13, similar views of the adjustable spreading shares;

Figure 12, a side view of thesod-cutting blade and anchor plate;

Figure 14, a perspective view of a serrated edge form of weed cutter; and

Figure 15, a similar view of a plain edge weed cutter.

Referring now in detail to the drawings, A designates the plow handle, B the plow- 1924. Serial No. 726,150;

foot or body, and C the plow-tongue, all of wood.

. The top and sides of the forward portion of} the foot or body B all taper relatively gradually to the tip, and apoint 1 having the reinforcing rib 3 and shank 4- is to be arranged thereon by having its wings of its point arranged substantially inv engagement with. the tip. of foot B'. The rear part of said shank 4: is. bifurcated and receives the forward lower portion of the vertical sod-cutting blade 9, whereby the point 1 and its shank 4 will be held against wobbling. Tov apply, the binding collar 2 having a hinged forwardly inclined upper strap, as shown in Fig. 4, is arranged loosely on the tip. of foot B, the shank 4is then. passed between the upper strap. of said hinged bindingcollar 2 and the upper inclined face of foot'B. until the crotch of its. bifurcation engages against the forward lower portion of plate 9: and the wings of the point 1 are substantially inenga-gement with the tip of foot- B, when the binding collar will be forced up, on the tapered tipv of foot B. until it makes biting engagement. therewith and with said shank 4. .Any forward pulling of the shank 4, because of its frictional engagement with the upper strap of collar 2, will tend to swing the latter about its hinge connection, thus inoving it into tighter contact with the shank 4 and automatically gripping it to prevent its accidental displacement or removal.

To the rear of the collar 2 is mounted the plate 5 carrying the 'weeder or grubbing blades 6, or 6 of modified form shown in Fig. 15, preferably integral therewith, said plate 5 being secured in place by suitable screws or pins 7 passing through perforated Wings or lugs 8 of plate 5 into the body of B.

Next behind plate 5 is arranged the knife 9 which is driven into the foot or body B for a portion of its body, and the plowshares 10 are secured to this and to the respective side portions of the foot B by means of suitable screws, bolts, or pins 11 and 12.

The rear portions of these shares 10 are provided respectively with perforations 13.

Supporting arms or brackets 14 secured to the body B well to the rear of large binding collar 20 by pins or screws 15 have perforated upper end portions adapted to be secured to the respective shares 10 by means of bolts 16 passing through the perforations 13 respectively and receiving cooperating nuts 17.

The adjustable spreading blades or shares 18 are pivotally held at their lower front ends to the shares 10 respectively by the respective screws, pins or bolts 12 and are provided with arcuate slots 19, registering respectively with perforations 13, to receive the stems of bolts 16, so that by loosening up the respective nuts 17 the blades 18 may be adjusted to the desired position, when the nuts 17 are to be tightened up until they bind tightly against the blades 18, locking the latter in such adjusted position.

The rear binding collar 20, in interior size and shape, corresponds closely to the crosssectional shape and size of the foot or body B at the rear end of the tapered portion thereof and is forced thereon until in tight binding engagement therewith.

Having thus described my invention, What I claim as new and desire to secure by United States Letters Patent is:

1. A native plow having a tapered foot, a point having a shank adapted to lie against the upper forwardly inclined face of said foot, and a binding collar having a hinged portion and applied to said foot and shank and adapted to be forced rearwardly thereof to hold said foot and shank in tight engagement in immovable relation,

' the forward hinging motion of said hinged portion incidental to the unintentional withdrawal movement of sald shank serving to draw said hinged portion into tighter engagement with said shank and prevent its unintentional displacement.

2. A native plow having a tapered foot, a vertically disposed element extending from the upper face'of said foot, a point havinga bifurcated shank lying against the upper forwardly downwardly inclined face of said foot, and a binding collar applied to said foot and shank and adapted to be forced rearwardly thereof to hold said foot and shank in arranged relation, the bifurcations of said shank receiving between them a portion of said vertically disposed element, whereby wobbling of the shank is prevented. Y

3. A native plow having a tapered foot, a vertically disposed element extending from the upper face of said foot, a point having a shank formed with a bifurcated rear portion and lying against the upper forwardly downwardly inclinedface of said foot, said rear portion receiving said vertically disposed element between its bifurcations, and a binding collar having a hinged portion and applied to said foot and shank and adapted to be forced rearwardly thereof to hold said foot and shank in tight engagement, the hinged portion of said collar being automatically progressively drawn. lnto tighter engagementwith said shank as the shank is moved forward unintentionally.

In testimony whereof, I have signed my name to this specification at Mexico city this th day of June, 1924:.
